    In this paper, we propose a LexOnt, a semi-automatic ontology creation tool for high-level service ontology. LexOnt uses the Programmable Web directory of services as its corpus of data along with Internet sources such as Wikipedia in order to generate common terms within a service domain and determine generic properties for classification. Currently, Programmable Web classifies services in a flat... View full abstract»

    Hadoop has shown great power in processing vast data in parallel. Hive, the database on Hadoop, enables more experts to process relational data by providing sql-like interface. However, Hive does not provide an efficient approach for join, a common but expensive operator in relational database. Due to the importance of join, this paper proposes a novel hybrid algorithm, HJA, which can help to auto... View full abstract»

    With the decrease of hardware production costs, putting connection capabilities to appliances has become affordable. At the same time, the widespread adoption of the Web has gained on Internet users. At the convergence of these two facts the idea of a ``Web of Things" has emerged, unleashing the current Internet of Things solutions by exposing connected objects as Web resources. While quite promis... View full abstract»

    Request Permissions | Click to expandAbstract | PDF file iconPDF (249 KB) |  | HTML iconHTML  

    The task of topical classification of Web queries is to classify Web queries into a set of target categories. Machine learning based conventional approaches usually rely on external sources of information to obtain additional features for Web queries and training data for target categories. Unfortunately, these approaches are known to suffer from inability to adapt to different target categories w... View full abstract»

    The Semantic Web (also known as Web of Data) is growing fast and becoming a decentralized knowledge platform for publishing and sharing information. The web ontologies promote the establishment of a shared understanding between data providers and data consumers, allowing for automated information processing and effective and efficient information retrieval. The majority of existing research effort... View full abstract»

    Term weighting strategy plays an essential role in the areas related to text processing such as text categorization and information retrieval. In such systems, term frequency, inverse document frequency, and document length normalization are important factors to be considered when a term weighting strategy is developed. Term length normalization is proposed to give equal opportunities to retrieve ... View full abstract»

    In this paper we propose a methodology whereby we semantically align heterogeneous databases without changing the databases. The alignment achieved is on the data instance level, which does not require the semantics of the data at the type level. We first introduce semantic alignment in the context of our databases research project then discuss in details how heterogeneous databases that are seman... View full abstract»

    A key challenge of Web Service (WS) composition is how to ensure reliable execution. Due to their inherent autonomy and heterogeneity, it is difficult to reason about the behavior of service compositions especially in case of failures. Therefore, there is a growing interest for verification techniques which help to prevent service composition execution failures. In this paper, we present a proof a... View full abstract»

    Clustering is an important technique for intelligence computation such as trust, recommendation, reputation, and requirement elicitation. With the user centric nature of service and the user's lack of prior knowledge on the distribution of the raw data, one challenge is on how to associate user quality requirements on the clustering results with the algorithmic output properties (e.g. number of cl...

    Multi-dimensional range queries are fundamental requirements in large scale Internet applications using Distributed Ordered Tables. Apache Cassandra is a Distributed Ordered Table when it employs order-preserving hashing as data partitioner. Cassandra supports multi-dimensional range queries with poor performance and with a limitation that there must be one dimension with an equal operator. Based ... View full abstract»
