Lexical-semantic resources are fundamental building blocks in natural language processing (NLP). Frequently, they fail to cover the informal vocabulary of web users as represented in user-generated content. This paper aims at exploring folksonomies as a novel source of lexical-semantic information. It analyzes two prototypical examples of folksonomies, namely BibSonomy and Delicious, and utiliz...

This paper describes a medical concept normalisation system developed for the 2nd Social Media Mining for Health Applications Shared Task 3. The proposed system contains three main stages: lexical normalisation, word vectorisation and classification. The lexical normalisation stage was aimed to correct spelling mistakes and maximise the coverage of pre-trained word embeddings utilised to genera...

We present a new version of a Graphical User Interface (GUI) called DiCoInfo Visuel, mainly based on a graph visualization device and used for exploring and assessing lexical data found in DiCoInfo, a specialized e-dictionary of computing and the Internet. This new GUI version takes advantage of the fundamental nature of the lexical network encoded in the dictionary: it uses logic based methods...

In this paper we claim that an integration of FrameNet and WordNet will improve interoperability, user-friendliness and usability of both lexical resources. If the former provides a sophisticated representational structure compared to a narrow lexical coverage, the latter on the other side supplies a dense network of word senses and semantic relations although not supporting advanced accessibil...

Lexical ambiguity is an important source of inefficiency for wide-coverage HPSG parsing. In this paper, we propose a lexical analysis filter which removes unlikely lexical categories. The filter is implemented as a straightforward HMM n-gram POS-tagger, which computes the ’a posteriori’ probability of each lexical category. A lexical category is removed if a competing lexical category is suffic...

In this report we show that a lexicon can be designed in such a way that lexical coverage can be maximized by real-time lexicon expansion and a limited word part lexicon for Dutch speech recognition. More specifically, we describe how the lexicon is designed and how the real-time expansion module was built and tested. Tests were performed using a 36.000 entries lexicon. The test results show th...

In this paper, we introduce the Léxico de Formas Flexionadas del Español (Leffe), a wide-coverage morphological and syntactic Spanish lexicon based on the Alexina lexical framework. We explain how the Leffe has been created by merging together several heterogeneous lexicons and how the Alexina lexical framework has been applied to Spanish. We also introduce a semi-automatic technique based on a...

Because of the emphasis on different languages and different subject areas the research has focused on the development of general purpose, re-usable techniques. The CRL/Brandeis group have implemented statistical methods for focusing on the relevant parts of texts, programs which recognize and mark names of people, places and organizations and also dates. The actual analysis of the critical par...

The Chinese language has many special characteristics which are substantially different from western languages, causing conventional methods of language processing to fail on Chinese. For example, Chinese sentences are composed of strings of characters without word boundaries that are marked by spaces. Therefore, word segmentation and unknown word identification techniques must be used in order...
