Analysis and Generation of Emotion in Texts

Prof. Dr. Diana Inkpen, University of Ottawa, Canada 

Abstract -- Texts have been classified by topic, genre, sentiment orientation (positive or negative opinions), or even by the gender of the authors. I will focus on classifying texts by the emotion that they  express or by the mood of the author at the time of writing. Results on a blog collection will be presented in detail. In order to achieve good results when classifying texts into 132 moods, I propose a hierarchical classification approach. The idea of automatically generating texts that express a given emotion or mood will also be discussed. These texts can be used in digital games where written messages are exchanged, in order to create the impression that the characters have personality.

The Implications of Collective Intelligence and Nature-Inspired Computing in Knowledge Engineering

In memory of Prof. Dr. Reind van de Riet

Though semantics appear to gain only in the last decade an immense popularity in highly technical fields in computer science such as the Semantic Web, Ontology and Knowledge Engineering, Information Retrieval, Web and text mining, the term ''semantics'' has a long history and tradition in computer science. To this extent, semantics reflect the meaning of programs and functions, which has been categorised, throughout the history of computer science, as denotational, operational or axiomatic semantics. 

Broadly speaking, the term semantics denotes a problem of understanding what a sign, mark, token or systems of symbols of higher complexity may signify. It is by no means a coincidence that the pursuit of meaning in terms of the study of the interpretation of signs and symbols became the holy grail of many other fields of inquiry including philosophy, linguistics, mathematics, psychology, biology, physics.

Despite the fact that many, and partly controversial, views, of the role and interpretation of a system of symbols emerged, particularly in philosophy, psychology and linguistics, it seems that there is a general agreement upon two fundamental issues: (S1) meaning can be complete only within some certain elements of context, which generate a system and points of reference, (S2) the choice of an appropriate system of symbols and their interconnections as capable of incorporating and emitting the right semantics is of paramount importance for harnessing the complexity of the system.

For instance, natural language has long been studied as the carrier of meaning and meaningful communication, which results from the synthesis of words, phrases, sentences and larger units of discourse.  The view of semantics taken, however, ranges from the external to internal to the natural language factors of interpretation. While the latter derives meaning from the utterance of other words in the language construct to form a context to resolve phenomena of indexing and lexical anaphora, the first is attributed to cognitive linguistics as well as the philosophy of language and adheres meaning to a language according to a toolbox the importance of whose element lie in the way they function rather than their attachment to things (Wittgenstein, Quine, Davidson). For instance, the way expressions like ''red wine'' and ''white wine'' derive their meaning out of a contrastive view rather than a literal interpretation attributed to the colours ''red'' and ''white''.  

Though the importance of the existence of some elements of context and the view that no word has a value without another word in its vicinity, the problem of semantic underspecification inherited to all natural languages has been highlighted by almost all contemporary views taken in linguistics. However, the quest for the most suitable natural language as the  most ideal system of linguistic symbols and interconnecting rules and, therefore, as a carrier of meaning and semantics with as less as possible complexity went on. For this purpose, linguists studied Sanskrit, a historical Indo-Aryan languages, which functioned as a liturgical language of Hinduism and Buddhism, in the realm of the most perfect system of syntax and semantics. 

The complexity of the language, however, became an issue. On the other extreme, Indian views on language, especially the Nyaya, view the words merely as indicators and not carriers of meaning. Is this a more pragmatic view and does the Nyaya language become less complex as a system of symbols? Is natural language the appropriate platform for expressing meaning at all? The profound answer for some philosophers (Pierre Levy) is negative and, perhaps, IEML (Information Economics Modelling Language) is the right platform for expressing of semiotic concepts.

The same sort of questions, which investigate the potential relationship between S1 and S2, has been witnessed in other disciplines as well. For instance, in mathematics, the choice of the Babylonians of an arithmetic system on the basis of the number 60, though grounded on nature and their knowledge of astronomy, which also heavily impacted the contemporary way of counting time (an hour divided in 60 minutes, 60 seconds, etc.), the system became unnecessarily complicated when it comes to arithmetic operations. 

The same holds for the Roman arithmetic system, which was based on combinations of letters. Instead, the Arabic arithmetic system, as based on the digits 0..9, prevailed, since it is claimed that it is more efficient in terms of interpretation of the symbols and the magnitude of potential expressions with only 9 symbols (digits). There is no need to introduce too many symbols in order to move to higher spheres of numbers. In this context, interpretation of the symbols is bound with the position of a digit within a number, e.g., interpretation of 9 within 90 and 900. 
However, philosophers claim that if there is anything like a less complex and more real semantic system than mathematics, this should anchor meaning at some system of reference to real objects and entities and what really exists. The driving question has been:  have you ever seen a 9 or 10 as objects or entities around you? Though promising, it soon became apparent that anchoring semantics at what  really exists became a tough question in metaphysics and ontology as well as in logic, which relates semantics with the notion of truth. It is not a coincidence that despite the fact that logic and ontology are important areas of philosophy covering large, diverse and active research projects, they both come with different conceptions as briefly explained in the following paragraphs.

Overall, we can distinguish among four notions of logic: (L1) the mathematical study of artificial formal languages, (L2) the study of formally valid inferences and logical consequence, (L3) the study of logical truths, (L4) the study of the general features or forms of judgement. Similarly, we can distinguish among four notions of ontology: (O1) the study of ontological commitment, i.e., what we and the others are committed to, (O2) the study of what there is, (O3) the study of the most general features of what there is and how the things there relate with each other in the metaphysically most general ways, (O4) the study of meta-ontology, i.e., saying what task it is that the discipline of ontology should aim to accomplish, if any, how the question it aims to answer should be understood, and with what methodology they can be answered.

Though it is out of the scope of this manuscript to go deeper into the various past and ongoing debates about the ramifications of the relations among the different conceptions as well as the overlapping areas between logic and ontology, it is worth mentioning the interwoven quest as to which extent logic can prove the existence of entities or objects, which ultimately led to the quest for proof of further metaphysical entities, by simply relying on conceptual truths. At this point, it is worth mentioning Frege's position that numbers are objects and arithmetic is logic implying the existence of entities. There is also a close relationship between this debate and a common criticism that standard formal logics in the sense of (L1) will not be able to capture the logical truths in the sense of (L2) (see also debate about the status of an empty domain in the semantics of first and second order logical systems).

On the other hand, formal ontologies have been invented as theories to give precise definitions and descriptions of entities, their properties and their interrelationships. To this extent, instead of trying to prove the existence of entities or objects on the way paved by logic, they simply put the emphasis on the description of what exists. Despite their philosophical use to become descriptive of what exists, their contemporary use is to provide a framework to represent information in a useful way for humans and machines. 

Though merely descriptive in their nature, formal ontologies could not avoid the risk of becoming a system of higher complexity, especially when they were meant to act as frameworks in order to answer any kind of existential questions. The famous debate in Ontology between Carnap and Quine in the first half of the 20th century was shedding some more light into this problem. Carnap was denying the existence of an Ontology and was suggesting the creation of frameworks as formal languages that have a clearly defined relationship to experience or empirical evidence as part of their semantics. According to Carnap, it was a matter of usefulness and practicality which framework should be selected by scientists to formulate their theories in. Moreover, there is no correct framework that truly mirrors the world as it is in itself. Nevertheless, Carnap's intriguing position contrasted the 'structure of thought explains the structure of the world' thesis (Kant, Critique of Pure Reason).

Fortunately or unfortunately,  the haunted quest about the ideal relationship between S1 and S2 has been revived with the emergence of the Semantic Web and other contemporary forms of computing like Social and Cloud computing. It is characteristic that description logics as a formalism underpinning OWL as an ontology language for the Semantic Web went through three main phases: (1980-1990) implementation of systems which employed the so-called structural subsumption algorithms, (1990-1995) introduction of a new algorithmic paradigm, the so-called tableau-based algorithms, (1995-2000) development of inference procedures for very expressive description logics.  In all these phases, the driving force has always been to harness the complexity as bound with algorithmic decidability of the inference systems, which was increasing from polynomial to exponential with the expressiveness of descriptions. In contrast, researchers and developers turned to more pragmatical solutions and systems such as folksonomies, tagging, personalised annotations. 

However, the answer begging question still remains: Is harnessing of complexity in semantic systems and computing a  problem with the current von Neumann architecture and Turing machines? Could Quantum Computing or other forms of computing settle this issue? Or, is it simply the wrong approach to the relationship between S1 and S2?
In our research, entrepreneurial and world knowledge contribution, we kept on providing different angles to the definition of scalable computational semantics and systems in respect with S1 and S2. Recently, we embarked on investigations of the relationship between geometry and meaning, i.e., grounding meaning in space and time, on extension of FCA (Formal Concept Analysis) to embed perspectives as a mathematical theory underpinning lattices of concepts, as well as nature inspired computing. The latter varies from the design and specification of formal languages resembling the way meaning arises from DNA-structures as well as in economics (Pierre Levy) to the study of phenomena of semantic communication in swarms, particles organisation, cell biology and other higher forms of life in nature.

Though it is hard to see at a first glance the relationship between, e.g., biology and the modern Internet and computing in general, inspiration and promising approaches are well sought after at systems level. For instance, in modern biological research, networks are ubiquitous at all levels of scale. On top of a network of genes, there is a protein interaction network, signalling networks and metabolic networks, which themselves underpin arrays of interacting networks that link cells together. 

Could such biological networks inform our understanding of our cyberspace infrastructure? Can social networks and collective intelligence on the Web be understood on the premise of evolution principles of biological networks, which lead to higher forms in life? Is the answer for a proper relationship between S1 and S2 in the construction of semantics driven systems hidden behind the secrets of nature and how complexity is harnessed on the premise of layered networks and equilibrium theories of ecosystems? Is the conception of the Internet, Information and Software Systems as a Digital (Software) Ecosystem, something which evolves out of self-managing entities with simple rules of the evolution game and boundaries, as opposed to top-down approaches of knowledge engineering in traditional AI, the key towards meaningful systems with a controllable complexity?

Knowledge Representation within an Intelligent Tutoring System

Dr. Helmut Horacek - Saarland University, Saarbr├╝cken, Germany

Abstract -- Intelligent tutoring systems, though quite successful in a variety of applications, are typically limited with respect to the generality of their problem-solving methods and in their communication capabilities. Aiming at exploring the prerequisites for future, more powerful tutoring systems, we present techniques for representing knowledge within such a system that allow for reasoning about more complex problem-solving situations and that enable exible communication in natural language. The domain of application is teaching a student how to prove mathematical theorems.

An Overview of Distributed Usage Control

Prof. Dr. Alexander Pretschner -- IESE and TU Kaiserslautern, Germany

Abstract -- Usage control generalizes access control to what happens to data in the future (\delete after thirty days," \do not copy," \notify owner upon access.") Distributed usage control is about defining and enforcing usage control requirements on data after giving it away. It is relevant in the areas of data protection, the management of intellectual property, the management of secrets, and compliance with regulations. In this extended abstract, we provide an overview of the field. We introduce fundamental concepts, requirements, policy specifications, policy analyses, dissemination models, the enforcement of usage control requirements at different levels of abstraction, and the challenges ahead.

Modeling Semantic Knowledge in Erlang for Refactoring

Prof. Dr. Zoltan Horvath -- Eotvos Lorand University, Budapest, Hungary

Abstract -- ~RefactorErl is a refactoring tool for the Erlang programming language. Refactorings have to collect many kinds of information that appear scattered in the source code. Therefore, when designing a refactoring tool, the most important concern is how the program is represented so that the many layers of intertwined information can be accessed conveniently. Such information strongly depends on the language, therefore we have opted to develop a language specic model for Erlang. This model encompasses the expert knowledge necessary for refactoring Erlang programs by describing the connections between the diverse pieces of information.

''What next in Knowledge Representation?''
 
Prof. Dr. Vasile Rus, University of Memphis, USA

Abstract -- We argue in this talk that searching for and proposing a good knowledge representation is a fine balancing act between two types of opposing forces: computational and ergonomic requirements. On one hand, we need representations that are "computer-friendly", i.e. well-structured, rigorous, and unambiguous, such that automated processing of knowledge is straightforward. On the other hand, the representations must be ergonomic, i.e. fit the humans as the ultimate input providers and consumers of the results of methods that automatically process knowledge. Natural language is the most ergonomic of all knowledge representations. That is, a good knowledge representation should be as close as possible to the human language to be ergonomic. However, natural language is open-structure, flexible, and ambiguous - the opposite of a computational representation. There seems to be an answer to this knowledge representation impossibility/paradox. We argue in this talk that natural language-based knowledge representations (~NL-based KR) are good candidates for a good knowledge representation in particular for processing knowledge in verbose domains such as conceptual physics, biology, and computer literacy as opposed to more abstract domains such as mathematics. We review in this talk several natural language-based knowledge representations, both statistical and symbolic, and then focus on an extremely powerful ~NL-based representation whose properties will be discussed. The use of these representations in various applications is illustrated.

|Description|Show tiddlers one at a time with automatic permalink, or always open tiddlers at top/bottom of page.|
This plugin allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one tiddler displayed at a time.
!!!!!Documentation
>see [[SinglePageModePluginInfo]]
!!!!!Configuration
<<<
<<option chkSinglePageMode>> Display one tiddler at a time
><<option chkSinglePagePermalink>> Automatically permalink current tiddler
><<option chkSinglePageKeepFoldedTiddlers>> Don't close tiddlers that are folded
><<option chkSinglePageKeepEditedTiddlers>> Don't close tiddlers that are being edited
<<option chkTopOfPageMode>> Open tiddlers at the top of the page
<<option chkBottomOfPageMode>> Open tiddlers at the bottom of the page
<<option chkSinglePageAutoScroll>> Automatically scroll tiddler into view (if needed)

Notes:
* The "display one tiddler at a time" option can also be //temporarily// set/reset by including a 'paramifier' in the document URL: {{{#SPM:true}}} or {{{#SPM:false}}}.
* If more than one display mode is selected, 'one at a time' display takes precedence over both 'top' and 'bottom' settings, and if 'one at a time' setting is not used, 'top of page' takes precedence over 'bottom of page'.
* When using Apple's Safari browser, automatically setting the permalink causes an error and is disabled.

Recent years development of industry brought out the need of an international airport in Cluj-Napoca. There are some international companies that already operate regular fligths with destinations in major western european cities, as well as our national operator Tarom connecting Cluj-Napoca with Bucharest and some other romanian cities.

Because of the diversity of destinations and the acceptable distance between Cluj-Napoca and Budapest international airport there are travel agencies which operate regular minibus connections between these two objectives:

It offers a higher level of education enabling students access to modern facilities.

The Campus building, where the events will take place, is situated at the 58-60 Teodor Mihali Str. and represents one of the most recent investments offering the best academic environment. It resides in 5 amphiteatres, 10 course rooms, 28 seminar rooms, 31 computer science laboratories, 10 laboratories for economical sciences, 4 laboratories for foreign languages study, a library and a cafeteria.

~Cluj-Napoca is the biggest city in Transylvania and one of the biggest and most important ones in Romania. It represents an important railway node with connections for all major destinations in the country or central and eastern Europe. Available connections can be found from the train timetable.

!How to Get There


Travel from ~Cluj-Napoca Airport takes between 45-60 minutes, and approximately 15-30 minutes from central parts of the city. Recommended airport transport is by bus shuttle. The nearest bus station is Campus Universitar. Transport details, maps and airport directions are available [[HERE|http://www.ratuc.ro/]].

 What next in Knowledge Representation?

Abstract -- We argue in this talk that searching for and proposing a good knowledge representation is a fine balancing act between two types of opposing forces: computational and ergonomic requirements. On one hand, we need representations that are "computer-friendly", i.e. well-structured, rigorous, and unambiguous, such that automated processing of knowledge is straightforward. On the other hand, the representations must be ergonomic, i.e. fit the humans as the ultimate input providers and consumers of the results of methods that automatically process knowledge. Natural language is the most ergonomic of all knowledge representations. That is, a good knowledge representation should be as close as possible to the human language to be ergonomic. However, natural language is open-structure, flexible, and ambiguous - the opposite of a computational representation. There seem to be an answer to this knowledge representation impossibility/paradox. We argue in this talk that natural language-based knowledge representations (NL-based KR) are good candidates for a good knowledge representation in particular for processing knowledge in verbose domains such as conceptual physics, biology, and computer literacy as opposed to more abstract domains such as mathematics. We review a series of natural language-based knowledge representations, both statistical and symbolic, and then focus on an extremely powerful representation whose properties will be discussed. The usage in various applications of the discussed representations is also provided.
