MediaCampaignpsilas scope is on discovering and inter-relating advertisements and campaigns, i.e. to relate advertisements semantically belonging together, across different countries and different media. The projectpsilas main goal is to automate to a large degree the detection and tracking of advertisement campaigns on television, Internet and in the press. For this purpose we introduce a first prototype of a fully integrated semantic analysis system based on an ontology which automatically… Show more

MediaCampaignpsilas scope is on discovering and inter-relating advertisements and campaigns, i.e. to relate advertisements semantically belonging together, across different countries and different media. The projectpsilas main goal is to automate to a large degree the detection and tracking of advertisement campaigns on television, Internet and in the press. For this purpose we introduce a first prototype of a fully integrated semantic analysis system based on an ontology which automatically detects new creatives and campaigns by utilizing a multimodal analysis system and a framework for the resolution of semantic identity.

In this paper we report on the use of feature structures to represent the linguistic information of a corpus. This approach has been adopted in TyPTex, a project which aims at providing a generic architecture for corpora profiling. After a brief overview of the Typtex project, we show that corpora exploration requires manipulating linguistic features in order to obtain a required level of linguistic information or changing the set of features to get a new point of view on the data. We show that… Show more

In this paper we report on the use of feature structures to represent the linguistic information of a corpus. This approach has been adopted in TyPTex, a project which aims at providing a generic architecture for corpora profiling. After a brief overview of the Typtex project, we show that corpora exploration requires manipulating linguistic features in order to obtain a required level of linguistic information or changing the set of features to get a new point of view on the data. We show that feature structures formalism can help the building and management of linguistic features with Meta-Rules based on unification. Finally, we provide an example of marking which uses a mixed approach between projection of information from a static lexicon and contextual marking via Meta-Rules. Results tend to show that the use of feature structures can improve the coverage and reliability of the marking. Show less

The World Wide Web has grown so big, in such an anarchic fashion, that it is difficult to describe. One of the evident intrinsic characteristics of the World Wide Web is its multilinguality. Here, we present a technique for estimating the size of a language-specific corpus given the frequency of commonly occurring words in the corpus. We apply this technique to estimating the number of words available through Web browsers for given languages. Comparing data from 1996 to data from 1999 and 2000,… Show more

We apply this technique to estimating the number of words available through Web browsers for given languages. Comparing data from 1996 to data from 1999 and 2000, we calculate the growth of a number of European languages on the Web. As expected, non-English languages are growing at a faster pace than English, though the position of English is still dominant. Show less

The increasing use of methods in natural language processing (NLP) which are based on huge corpora require that the lexical, morpho-syntactic and syntactic homogeneity of texts be mastered.

We have developed a methodolog The increasing use of methods in natural language processing (NLP) which are based on huge corpora require that the lexical, morpho-syntactic and syntactic homogeneity of texts be mastered. We have developed a methodology and associate tools for text calibration or "profiling" within the ELRA benchmark called "Contribution to the construction of contemporary french corpora" based on multivariate analysis of linguistic features. We have integrated these tools within a modular architecture based on a generic model allowing us on the one hand flexible annotation of the corpus with the output of NLP and statistical tools and on the other hand retracing the results of these tools through the annotation layers back to the primary textual data. This allows us to justify our interpretations.y and associate tools for text calibration or "profiling" within the ELRA benchmark called "Contribution to the construction of contemporary french corpora" based on multivariate analysis of linguistic features.

We have integrated the RASP system with the UIMA framework (RASP4UIMA) and used this to parse the XML-encoded version of the British National Corpus (BNC). All original annotation is preserved, and parsing information, mainly in the form of grammatical relations, is added in an XML format. A few specific adaptations of the system to give better results with the BNC are discussed briefly. The RASP4UIMA system is publicly available and can be used to parse other corpora or document collections… Show more
