    Abstract: A wireless network comprises access points (APs) implementing roaming by way of handover of wireless devices between APs. Handover events over an analysis time interval are extracted from a wireless network log of the wireless network. Each handover event comprises a source AP from which a wireless device disconnects and a destination AP to which the wireless device connects. At least one handover frequency (HF) network topology graph is constructed fro the analysis time interval from the extracted handover events. The graph has nodes representing at least a subset of the APs of the extracted handover events and edges connecting pairs of nodes with each edge having a weight representing a count or frequency of handover events between the APs represented by the pair of nodes connected by the edge. A network diagnostic or visualization task is performed using the HF network topology graph.

    Abstract: A system for generating a query includes a term unit (1) for extracting a term from at least one input document (51), to obtain an extracted term. A category unit (2) is arranged for associating the extracted term with a category that is semantically related with the extracted term. A query unit (3) is arranged for generating a query in dependence on the extracted term and the category. The query unit (3) includes an additional term unit (4) for generating at least one additional search term based on the category, and the query unit (3) is arranged for including the additional search term in the query. A submit unit (5) is arranged for submitting the query to at least one search engine (50), to obtain a plurality of found documents.
