- | ** 2. Exploring reference citation of HDS articles** | ||
- | The objective is to reconcile HDS bibliographic data with SwissBib. | ||
+ | ===== Named Entity Recognition ===== | ||
+ | We used web-services to annotate text with named entities:\\ | ||
+ | - Dandelion\\ | ||
+ | - Alchemy\\ | ||
+ | - OpenCalais \\ | ||
- | ===== Named Entity Recognition ===== | ||
+ | {{: | ||
+ | |||
+ | Named entity mentions (persons and places) are matched against entity labels of HDS entries and directly linked when only one HDS entry exists. | ||
+ | |||
+ | Further developments would includes:\\ | ||
+ | - handling name variants, e.g. 'W.A. Mozart' | ||
+ | - real disambiguation by comparing the newspaper article context with the HDS article context (a first simple similarity could be tf-idf based)\\ | ||
+ | - working with a more refined NER output which comprises information about name components (first, middle,last names)\\ | ||
+ | |||
+ | === Some statistics === | ||
+ | In the 23.622 articles of the year 1914 in «Le Temps digital archive» we linked 90.603 entities pointing to 1.417 articles of the «Historical Dictionary of Switzerland». | ||
+ | |||
+ | {{: | ||
+ | |||
+ | |||
+ | === Web Interface === | ||
+ | |||
+ | We developed a simple web interface for searching in the corpus and displaying the texts with the links.\\ | ||
+ | It consists of 3 views: | ||
+ | |||
+ | |||
+ | 1. Home\\ | ||
+ | {{: | ||
+ | \\ | ||
+ | 2. Search\\ | ||
+ | {{: | ||
+ | \\ | ||
+ | 3. Article with links to HDS, Wikipedia and dbpedia\\ | ||
+ | {{: | ||
+ | \\ | ||
+ | |||
+ | === Further works === | ||
+ | Further works would include:\\ | ||
+ | - evaluate and improve method.\\ | ||
+ | - apply the method to the Historical Dictionary of Switzerland itself for internal linking.\\ | ||

Swissbib queries can return Dublin Core, MARC XML or MARC in JSON format. Dublin core is the easiest to manipulate, but unfortunately it does not contain the entirety of the returned record. To access the full record, it is necessary to use either MARC XML or MARC JSON. | Swissbib queries can return Dublin Core, MARC XML or MARC in JSON format.

+ | === Further works === | ||
+ | This is only the first step of a more general work inside the HDS:\\ | ||
+ | * identify precisely each notice in an article (ID attribute to generate)\\ | ||
+ | * collect references with a separation by language\\ | ||
+ | * clean and refine the collected data\\ | ||
+ | * setup a querying workflow that keeps the ID of the matched target in a reference catalog\\ | ||
+ | * replace each matching occurence in the HDS article by a reference to an external catalog\\ | ||
