    Distributional Semantics
    Meaning representation through statistics

    Distributional Semantics

    Distributional semantics is built upon the assumption that the context surrounding a given word in a text provides important information about its meaning (Harris 1954), (Turney and Pantel 2010). Distributional semantics focuses on the construction of a semantic representation of a word based on the statistical distribution of word co-occurrence in unstructured data

    Query Mechanisms over Heterogeneous Databases

    Natural Language Processing

    The effort involved in querying heterogeneous and distributed third-party Linked Data sources on the Web creates barriers for data consumers. In order to query datasets, users need to discover the datasets of interest, understand the structure and vocabularies used in these datasets, and then finally formulate the query using the syntax of a structured query language (such as SPARQL or SQL). Ideally users should be able to express their information needs without being aware of the dataset vocabulary (or ‘schema’), delegating the query formulation process to a query engine.

    Semantic Web
    The Web of Data

    Semantic Web

    The Web is evolving into a complex information space where users have access to an unprecedent volume of information. The advent of Linked Data in the last years as the de-facto standard to publish data on the Web, and its uptake by early adopters, defines a clear trend towards a Web where users will be able to easily aggregate, consume and republish data.
