The following workshops will be hosted on September 21, 2012 in conjunction with KONVENS (click on a title for further information):
PATHOS - Practice and Theory of Opinion Mining and Sentiment Analysis
Organizers: Stefan Gindl, Robert Remus, Michael Wiegand
The goal of PATHOS is to attract researchers and developers in the
area of sentiment analysis and opinion mining. The workshop focuses
on (i) methods and resources for multi-lingual sentiment
analysis, (ii) dependencies of genre and domain in sentiment
analysis and its subtasks, (iii) sentiment analysis with
distinction of emotional categories, i.e. emotion analysis,
and (iv) opinion holder and opinion target extraction. While
there is an abundance of methods and resources available for English,
comparatively little research focuses on other languages or
multi-lingual sentiment analysis. In addition to language differences,
deviations across genres and domains require special treatment, but
are so far only seldom taken into account. Emotion analysis goes
beyond traditional sentiment analysis, giving insight into the
different emotional categories of an opinionated statement. Thus it is
not restricted to mere polarity identification but detects particular
feelings, such as “fear”, or “anger”, “hope” and “joy”. Opinion holder
and target extraction is the domain in sentiment analysis with
significant economic potential. It allows stakeholders to nail down
the exact source and target of criticism or praise. Exploiting this
knowledge helps improving products and services and can be considered
a tool for quality assurance.
PATHOS will serve as a platform for these particular sub-areas of sentiment analysis.
The workshop will be organized by the recently founded Interest Group on German Sentiment Analysis (http://synergy.sentimental.li).
Language Technology for Historical Text(s)
Organizers: Brigitte Krenn, Karlheinz Mörth, Thierry Declerck
The interaction between Human Language Technology (HLT) and Digital Humanities (DH) at large has been the focus of various projects and initiatives during the last years, aiming to bring forward language resources and tools for the Humanities, Social Sciences and Cultural Heritage.
The specific focus of LThist 2012 lies on the development of technology and resources required for processing historical texts. Contributors and participants are invited: (i) To compare and, to the extent possible, interchange data, tools, approaches, and standards that make historical texts accessible to automatic processing. In line with the general topic of Konvens2012, specific attention will be paid to the adoption of empirical methods. (ii) To discuss ways and strategies for shaping HLT resources (tools, data and metadata) in ways that are maximally beneficial for researchers in the Humanities.
In the workshop, historical texts are understood in two ways: Texts as documents of older forms of languages, and texts as documentations of historical content. Therefore the workshop will not only be concerned with questions of collecting, representing, processing and exchanging corpora of historical texts and respective tools, but also with finding ways to co-relate linguistic information with data representing extra-linguistic historical context.
Topic areas that will be addressed in LThist 2012 comprise (but are not limited to) methods and tools: for processing historical texts making use of rule-based as well as statistical approaches; for building corpora of historical texts and languages; for integrating multimedia and multimodal aspects (text and image) in historical corpora; for building concrete applications and creating concrete infrastructures supporting the collaboration between HLT and DH.
Recent developments and applications of lexical-semantic resources
Organizers: Stefan Engelberg, Claudia Kunze
The workshop aims to provide a forum for discussing recent developments and applications of various kinds of lexical-semantic resources including wordnets, ontologies, framenets, electronic dictionaries, internet lexicons, and other collaboratively built lexical semantic resources. Lexical-semantic contents serve as valuable sources of linguistic information for research and applications in natural language processing. Successful attempts to integrate and merge lexical resources have led not only to the mapping of lexical databases of the wordnet and framenet type but also to the creation of online dictionary networks of different sorts. Enhancing usability also means to provide data for the human user by new sophisticated access interfaces as well as to make these data available for different kinds of NLP applications. We welcome papers on the design, construction, extension, maintenance, merge, and validation of lexical-semantic resources and their application in linguistic research as well as natural language processing.
Standards for Language Resources - Ongoing Developments and Practical Applications
Organizers: Andreas Witt, Ulrich Heid
During the last years the need of automatically generated and
processed linguistic resources increased dramatically. An important
aspect is that the linguistic resources can be applied to different
purposes. Hence, the resources should be reusable and interoperable.
However, to achieve this, some of the fundamental problems will have to be addressed, such as the standardisation of linguistic resources. With the help of standards it can be defined, for example, how the linguistic data can be created, imported and integrated in a platform-independent way. Currently the relevant standardisation activities are conducted by international working groups of the International Organisation for Standardization (ISO).
The principal goal of the workshop is to present and to inform about the current status of ISO standards in the domain of language resources and language technology, and to discuss applications of these standards.
The workshop combines more tutorial-like information dissemination that allows participants to get acquainted with the standards, with more research-oriented presentations that provide use-cases and report about experience gathered through working with the standards.
The workshop program is now available online.
