AFP, which covers the current economic life of the major industrialised countries, transmits on average 400 dispatches per day on this flow. Their content is drafted in French in a journalistic style. Using this flow, Exoseme feeds various users concerning precise and varied subjects, for example, rating announcements, company results, acquisitions, sectors of activity, observation of competition, partners or clients, etc. 50 such themes have currently been developed.

First, it segments proper names during the morphological analysis. Second, it categorises proper names during the semantic analysis. Third, it is invoked by the filtering module to supply some more information needed for routing the dispatch.",

"text": "The segmentation of proper names enables the synctactical analyser to be relieved, particularly in the case of long proper names which contain grammatical markers (e.g. prepositions, conjunctions, commas, full stops). As illustrated in [4] , segmentation firstly prevents long proper names from undertaking pointless analyses. For example, for Caisse de \u00a2r6dit hgricole du Morbihan the analyser will provide two interpretations depending on whether Morbiha.n is attached to Cr6dit hgricole or to Caisse. Moreover, proper names often constitute agrammatical segments that sometimes confuse the synctactical analyser. For exam-ple, in the sentence The director of Dollfus, Mieg and Cie has announced positive results, the analyser has difficulties in finding that The director is the subject of announce if it does not know the company Dollfus, Mieg and Cie. In the Exoseme process, the Sylex syntactical analyser [3] delegates the segmentation of these agrammatical gaps to our proper name module.",

For example, the acronym SHF of Soci6t4 des Bourses Fran~aises omits the preposition \"des\", while the acronym BDF of Banque de France keeps the \"de\". In order for our processing module to recognise these words, we allocate a special attribute to them in the knowledge base.",

This module unifies and completes known techniques which enable to segment and categorise proper names.

Our system currently detects 90% of proper names in AFP dispatches and categorises 85% of them correctly.",

From the grammatical point of view, our exploration of the context is incomplete. For example, we do not categorise the unknown proper name in a complex case such as Its Belgian subsidiary specialising in flat products Nokia. From the semantic point of view, we do not use all the contextual data. For example, the sentence The company already serves Houston, Saint-Louis and Dallas should be sufficient to disambiguate Saint-Louis. We are currently accumulating examples in which the local context enables certain proper names to be categorised and/or to be disambiguated. Our next step will consist in tightening cooperation with the following layers in order to use the grammatical and semantic data they provide in the whole process.",
