档案数据库建设浅谈

档案数据库就是以特定方式组织起来的档案数据集合。具体地讲,就是为满足多个用户多种应用需要,按照一定的数据模型将本单位保管的档案信息存贮在计算机中以备使用的数据形式。档案数据库建设是档案信息资源建设的基础和核心,档案信息资源建设又是档案信息化建设的核心任务,是档案信息化建设取得实效的关键。加强档案数据库的建设与应用,加快推进档案信息资源的整合与共享,把档案目录数据建设好,并建好全文数据库,以满足快速检索利用的需要,是目前档案馆建设的一项至关重要而又十分迫切的任务。一、按照从实际出发的原则,搞好档案数据库建设…

Museums at the crossroad: Contributing to dialogue, curiosity and wonder in natural history museums

The first natural history collections opened to the public were inspired by a sense of curiosity and wonder about the products of nature. They were ‘cabinets of curiosities’ that offered a first-hand interaction between owner and visitors. Nowadays, these two facets of the museum experience—dialogue and wonder—have been lost, in part, due to the information overload coming via the media and the impersonal nature of the museum visit. This paper offers some reflections on the evolution of the museum visit, suggests some ways to rediscover this ‘sense of wonder’ and provides ideas on how to promote two-way communication with museum visitors. Two examples of exhibitions are offered as illustrations of the points discussed.     

Multilingual modeling of cross-lingual spelling variants

Technical term translations are important for cross-lingual information retrieval. In many languages, new technical terms have a common origin rendered with different spelling of the underlying sounds, also known as cross-lingual spelling variants (CLSV). To find the best CLSV in a text database index, we contribute a formulation of the problem in a probabilistic framework, and implement this with an instance of the general edit distance using weighted finite-state transducers. Some training data is required when estimating the costs for the general edit distance. We demonstrate that after some basic training our new multilingual model is robust and requires little or no adaptation for covering additional languages, as the model takes advantage of language independent transliteration patterns. We train the model with medical terms in seven languages and test it with terms from varied domains in six languages. Two test languages are not in the training data. Against a large text database index, we achieve 64–78 % precision at the point of 100% recall. This is a relative improvement of 22% on the simple edit distance.
