Automatic language identi cation in written text documents is an issue which deserves signi cant attention in the context of the ever-growing volume of web documents. This paper deals with language identi cation in the domain of electronic texts related to tourism. The proposed system is built on Hidden Markov Models (HMMs) that enable the modeling of character sequences. For this purpose, a pa...

Many prior studies have investigated the recovery of semantic arguments for nominal predicates. The models in many of these studies have assumed that arguments are independent of each other. This assumption simplifies the computational modeling of semantic arguments, but it ignores the joint nature of natural language. This paper presents a preliminary investigation into the joint modeling of i...

Ein ständig wachsender Zweig der Innovationsforschung versucht die Dynamik innerhalb von virtuellen Communities besser zu verstehen. Das Konzept Sense of Community (SOC), das in OfflineCommunities das Verhalten von Mitgliedern erklärt, leistet einen Beitrag zu diesem Verständnis und wird als Gefühl einer Verbundenheit mit der Gruppe und deren Mitgliedern beschrieben. Da dieses Konzept bisher no...

This paper presents Carnegie Mellon University’s experiments on the mixed named-page and homepage finding task of the TREC 12 Web Track. Our results were strong; we achieved the success using language models estimated from combining information from document text, in-link text, and information present in the structure of the documents. We also present experiments using expectations about poster...
