| − | FCS Aggregator is available [https:// | + | FCS Aggregator is available at [https://www.clarin.eu/contentsearch https://www.clarin.eu/contentsearch]. No login is required. |
| + | |||
| + | |||
| + | === Basic search === | ||
| + | To send a query and get search results it is enough to enter a search term and click the magnifying glass button or press the '''Enter''' key. The default search options will apply: all the available FCS collections in any language will be searched and up to 10 hits per collection will be displayed. | ||
| + | |||
| + | If you have navigated to Aggregator from [http://catalog.clarin.eu/vlo/ the VLO] and the resources selected in VLO are found among the corpora resources available (e.g. [http://catalog.clarin.eu/vlo/?wicket:bookmarkablePage=:eu.clarin.cmdi.vlo.pages.ShowResultPage&fq=collection:T%C3%BCbingen+Language+Resources&docId=http://hdl.handle.net/11858/00-1778-0000-0001-DDAF-D# TuebaDDC]), then the search will be performed only in those selected resources. | ||
| + | |||
| + | ===== Search options ===== | ||
| + | The default searching options are easily changed by using the control bar located underneath the Search form. | ||
| + | |||
| + | |||
| + | [[File:Aggregator-overview.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | The following search options are available: | ||
| + | |||
| + | *Specify language of the resource: <br/>Click on the left-most button in the options bar, initially displaying '''Any Language''', and a dialog box with multiple language options will be displayed. To select a language option, click on the desired language and then click on the '''Close''' button. There are currently three language filtering strategies, that can be changed by using the selector at the bottom of the dialog window; these strategies are: 1. only search in the collections known to have resources in the specified language; 2. search in all the available collections, then use a language guesser and display only the results having the selected language; 3. search only the collections having resources in the desired language, and then filter the results by using the language guesser. | ||
| + | <br/> [[File:Aggregator-language-dialog.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | *Specify collections to search in: <br/>By default all the corpora resources are selected. If you want to restrict your search to a specific set of resources, click on the middle button in the control bar, initially displaying '''All available collections''' and a dialog window will show up. This dialog provides the option to select and deselect all collections, or particular collections. | ||
| + | <br/> Some collections also have sub-collections, and the ones that do provide a link to expand and explore, select and deselect its sub-collections. | ||
| + | <br/> [[File:Aggregator-collections-dialog.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | <br/>The collections view also offers the option to search the collections attributes and thus filter the list of displayed collections to only those of particular interest. | ||
| + | <br/> [[File:Aggregator-collections-search.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | *Specify number of records per collection per request: <br/>By default, 10 records per collection is returned. You can change this number by using the right-most control of the control bar. More records can be retrieved at any time, in the focused view, when available. | ||
| + | |||
| + | |||
| + | === Search results === | ||
| + | |||
| + | Search results will start showing immediately after the search function is invoked. The query is sent to all the selected corpora and the search results from resources are displayed on the first responds - first displayed basis. Therefore, you can start inspecting the search results (the records) before all the corpora have returned a response. Progress bar at the top of the page gives an information about the awaiting responses. | ||
| + | The search results are initially displayed in a textual view. | ||
| + | <br/> [[File:Aggregator-results.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | <br/> The textual view can be toggled to a concordance view, with the searched term in the middle, and its left and right contexts. | ||
| + | <br/> [[File:Aggregator-results-kwic.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | <br/> The entire set of search results can be downloaded locally on your computer (click '''Download'''). Several formats are offered for exporting search results. | ||
| + | <br/> [[File:Aggregator-results-download.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | ===== Focused View ===== | ||
| + | |||
| + | For more information on a result set, click on the '''View''' button on the top-right of the result pane. This brings into focus the View dialog with more information on the collection that the results come from, and the option to download only the visible results. | ||
| + | <br/> [[File:Aggregator-view.png|center|600px]] | ||
| + | <br clear=all> | ||
| + | |||
| + | The '''More Results''' button at the bottom of this diablog will perform a new query request to the same collection with the same search term, and will retrieve and display the additional results. This process can be repeated until no more results are available. | ||
| + | |||
| + | To process the search results with the WebLicht application, click the '''Use WebLicht''' button and confirm by selecting the '''Send to WebLicht''' button. WebLicht can process result sets in a couple major languages. | ||
