    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 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 data base system is disclosed for storing meta-data about labeled predominantly non-text items in a collection of labeled predominantly non-text items (lpnt items). The system comprises a storage facility (10), a keyword generation facility (20) and a meta-data enrichment facility (30). The storage facility (10) stores respective meta-data for lpnt items (i) within said collection, said meta-data comprising at least one lpnt item classification (gi) and a 1pnt item description (Ti), said classification defining classes. The keyword generation facility (20), which generates keyword data for respective classes, comprises a retrieval module for retrieving terms from lpnt item descriptions of 1pnt items associated with said classes. The keyword generation facility (20) further comprises a term relevance determining module for assigning a relevance of said terms for said classes, for selecting terms from said retrieved terms on the basis of their assigned relevance and providing these selected terms as candidate keywords. The system further comprises a metadata enrichment facility (30) for adding a subset (Ki) of the provided candidate keywords (K(c)) as keywords to the meta-data of lpnt items of a class.

    Abstract translation: 公开了一种数据库系统，用于将关于标记为主要非文本项的元数据存储在标记为主要非文本项目（Ipnt项）的集合中。 该系统包括存储设备（10），关键词生成设备（20）和元数据富集设备（30）。 存储设备（10）存储在所述集合内的I项目（i）的各个元数据，所述元数据包括至少一个项目分类（gi）和1个项目描述（Ti），所述分类定义类别。 生成各类的关键字数据的关键词生成设备（20）包括检索模块，用于从与所述类相关联的1个项目的lpnt项目描述中检索条目。 关键字生成设施（20）还包括术语相关性确定模块，用于根据所分配的相关性来选择所述类别的所述术语的相关性，从所述检索的词语中选择术语，并将这些选定的词语提供为候选关键词。 该系统还包括用于将所提供的候选关键字（K（c））的子集（Ki）作为关键字添加到类的项目的元数据的元数据富集设施（30）。
