索引/內容來源

  • BASE采用哪種索引軟件?
    自2011年五月起,我們使用Solr/Lucene的開源搜索技術。在2011年5月之前使用的是Microsoft FAST (Fast Search And Transfer)的搜索引擎技術。
  • 添加到BASE索引需要滿足那些要求?
    我們索引所有類型的學術相關資源,以“開放存儲元數據收割協議(OAI-PMH)”所提供的元數據(metadata)。我們觀察到一些知識庫目錄,像是OpenArchives, ROAROpenDOAR等,以及知識庫軟件目錄,像是DSpaceOJS等,定期收割和索引這些信息源的內容。
  • 我如何推薦一個新的內容信息源?
    如果您是一位知識庫管理者或者一份學術電子期刊的編輯,而您在我們的內容來源列表(list of content sources)中或者在索引中(search in our index)發現不到您的內容來源信息,請透過“聯系方式(suggest source)”讓我們知道:您的知識庫名稱、知識庫主頁的URL網址,以及OAI接口的基本URL信息。我們將立即確認數據,并且反饋您是否您的內容來源可被索引。
    即使您不是知識庫管理者,您也可以建議新的內容來源。該信息源必需包括學術文獻以及應該全文免費(開放獲取)。請透過我們的“聯系方式”發送它的名稱和URL網址給我們,如果可能的話,包括OAI接口的基本URL信息。我們將確認內容來源是否符合我們的范圍,并且反饋給您。
  • 我如何設定OAI接口,好讓我的內容來源能被BASE索引呢?
    如果您想設定OAI接口,請見開放存儲協議網站上的“安裝指南(implementation guideline”。您可以在OpenArchives.orgWikipedia上發現更多有關OAI的一般信息。您可以容易地檢查是否您的知識庫符合BASE要求(OVAL)。
    如果您的內容來源是一份電子期刊,而且它在DOAJ(Directory of Open Access Journals上,則它將被BASE自動索引(我們定期索引DOAJ的內容)。您在?DOAJ-FAQ上可發現注冊到DOAJ上的程序。您也可以使用OJS軟件來提供您的期刊內容(在OJS上實現OAI接口),這些信息可到OJS website上參考。
  • My source does not provide an OAI interface. Is it possible to index the documents in BASE nevertheless?
    In case your source does not provide an OAI interface, upload your documents to aggregators like DataCite or Zenodo, to subject repositories like RePEC or add your open access journal to DOAJ. We are indexing these sources regularly. However, the best way to get your documents indexed by BASE is to provide an OAI interface - in this case we can assure fast and smooth indexing of your source and data from your source will be presented completely and in the best possible way.
  • 你們多久更新索引來源后的內容?
    我們每周更新所有索引來源。經過一段較大的時間間隔,所有內容都會完全重新收割和重新索引。
  • 為什么有些來源或者文獻索引不完全?
    如果數據源不被完全索引,通常與數據源的OAI接口出現故障問題有關。網頁可能看起來還可以,但是作為我們只索引OAI元數據(OAI-metadata)而不涉及網頁界面。您能通過我們的“聯系方式(contact form)”告知情況。如果您是知識庫管理者,請用我們的OAI檢查器(OVAL)進行確認。
  • 你們會刪除索引中的數據源嗎?
    所有數據來源都被定期檢查。如果數據源工作不正常,或者不提供任何開放獲取內容,它會被暫時或者永久刪除。

搜索/命中列表

  • 搜索/命中列表
    請見我們的“BASE使用說明(search help)”。
  • 我在已經索引的文獻中可以搜索全文嗎?
    因為時效和功能等因素,我們只有索引元數據(metadata),如文獻的題名、摘要等。所以無法對文獻進行全文搜索。
  • 我可以只搜索有開放獲取內容的文獻嗎?
    在執行搜索后,您可以縮小搜索范圍只限開放獲取內容。在“精煉搜索結果(Refine Search Result)”對話框中,點擊“獲取(Access)”。結果列表將被限定在那些數據提供者在元數據內注明為開放獲取的文獻。請注意到,因為這部分元數據信息的缺失,BASE系統只能從所有被索引的開放獲取文獻中,找到30%左右。
  • Why are open access documents in BASE not marked as open access?
    There is a three-step process of how a document indexed in BASE gets an open access status and is marked with an icon:
    1. The content source contains only open access documents. This will be recorded in the BASE-Source database (if known) and all indexed documents of the source are marked open access in BASE
    2. The metadata of an open access document contains a special set for open access documents in <record><header> in "setSpec" (e.g. "driver", "openaire" or "OpenAccess"). This set is entered into our database and all documents from this set are marked as open access.
    3. Open access documents are individually marked by the content provider in (either CC license or descriptive information such as "OpenAccess" etc.)
    If none of these three details are available, BASE cannot identify the document as open access.
  • Why can't I access the full text of a document?
    About 60% of the indexed documents in BASE are open access, the rest are mere metadata entries without full text or can only be accessed, if you are authorized for accessing this particular data source. You can search the metadata of all indexed documents. The authorization is always done by the content provider. If you don't have access to a full text although your institution supposedly is authorized, please contact your IT department or the content provider.
  • Why can't I access a document marked as "Open Access"?
    If a document is marked as "Open Access" but still not accessible, there is usually an error on the part of the data provider. We mark documents as "Open Access" according to the information received from the provider (e.g. corresponding details in the rights information or a CC license). We do not check individually whether this information is correct. If you come across a document that is not correctly labelled as "Open Access", please contact the data provider and point out the problem.
  • 當我獲取一份文獻時,為什么最后經常顯示“錯誤信息(Error Message)”呢?
    如果您得到404 error ("Page not found")網頁找不到,可能是文獻的網頁網址(URL)改變或者文獻近期已被刪除。經過學術知識庫而來的內容,應該提供永久性網址,而且文獻位置的改變或者刪除應該會通過OAI接口傳輸,所以實際上這種情況不常發生。所以可能是我們搜索結果列表中所顯示的文獻鏈接不可用。另一種可能的原因是內容提供者的服務器當前或者長期失效。如果您遇到這個問題,請您給我們留言(leave us a message)。我們會與內容提供者取得聯系,或者如果它長期有問題,我們就從索引中移除。
  • 什么是元數據?
    特指在學術環境中,您經常與之溝通的文獻的元數據。從技術層面和內容術語上,對一份文獻進行的一系列描述性指稱。元數據,像是:作者姓名、出版日期、摘要、語言,或者期刊名等,反映題名或者焦點議題的細節等。如果元數據可用,則您可以用作者進行特定搜索;而在結果列表中,您可以利用分類目錄來精煉搜索結果。
  • Metadata is broken. Can you correct it?
    If you find a mistake in the metadata, e.g. false or missing author names, titles, years or bugs in the character set (e.g. ? instead of a character) the content providers are responsible for this. We already correct obvious metadata errors with automated procedures during indexing, but a substantive check is impossible. It's best to contact the data provider directly if you find errors in a record.
    If the data record appears correctly at the data supplier, it may be that the data is delivered incorrectly via the OAI interface, which we use to index the data. It may also be that the operator has recently corrected the record. In this case, the data in the BASE results list is also corrected during the next indexing (usually within 1-2 weeks).
  • What does the link "claim" after the author name mean?
    If you are the author of a publication that is listed in a BASE results list, you can confirm the authorship for these publications via the link "claim". For this you must register once with our search engine (see personal login) and have an ORCID iD. If you do not have an ORCID iD yet, you can register for free by clicking on "claim" directly at ORCID. After registering, ORCID will provide you with an ID that allows you to uniquely identify your publications (even if the name is identical to another person, variants in the spelling of your name or name changes). You can also incorporate metadata of the publication (author, title, year of publication, etc.) directly into your publication list at ORCID. After "claiming", an icon ("ID") with a link to your profile at ORCID is displayed next to your your author name in BASE.

BASE網站

  • 為什么我經常最后看到德文頁面?
    BASE網頁會根據您事先選定的瀏覽器設定來呈現。更改這些設定較容易(例如,如果您使用Mozilla的“火狐(Firefox)”的話,可以選擇“性能(Preferences)”然后“設置(Settings)”等)。如果轉換到“English英文”作為優先語言,則BASE網頁就會立即呈現英文網頁。
  • BASE的網站網頁支持打印嗎?
    BASE網頁設計是, 當打印要求被傳送時,會自動轉換為打印版本。
  • BASE網站具有支持移動通訊設備(如手機等)的優化網頁嗎?
    The BASE pages are designed responsively and therefore always optimally displayed on a large monitor as well as on a tablet or smartphone.
  • 我需要安裝Javascript、 Java或者其它類似的軟件嗎?
    BASE網址網頁設計為不需要用戶安裝Javascript或 Java就能實現全部功能。
  • BASE對某些瀏覽器或者版本有網頁“優化”版本嗎?
    BASE不對任何類型瀏覽器或者版本進行限制。網頁根據標準規范(XHTML, CSS)設計,并且符合WCAGWCAG規則。
  • Why are some words underlined?
    Acronyms and abbreviations,e.g. the word BASE are provided with an explanatory text, the first time they appear in the text of a page. This is displayed when you place the mouse cursor over the word. In order to show where the word has been explained first, the word is shown underlined here.

ORCID

  • What is ORCID?
    ORCID (Open Researcher and Contributor ID) is a standard for unambiguously matching academic authors to their respective publications that is currently being established worldwide. The ORCID iD as persistent identifier allows, e.g. in case of identical names, name changes or name variants, the clear differentiation of author names. It can be used anywhere in the world and depicts affiliation changes throughout individual academic careers. Thus, it contributes to better visibility of authors and their publications, and more and more publishers and funding organisations are demanding that authors provide an ORCID iD.
  • What is ORCID’s Collect & Connect Program, and what are the badges that BASE was awarded in this program?
    Collect & Connect is ORCID's integration and engagement program, which sets out best practices to clarify implementation goals and expectations across sectors, standardize the user experience, improve understanding of trust in connections between ORCID and other identifiers, increase the efficiency and quality of integrations, and help achieve ORCID's vision through a community approach.

    In the context of ORCID's Collect & Connect program, BASE was awarded the following badges:

    ORCID Collect & Connect badge - Authenticate AUTHENTICATE
    BASE authenticates ORCID iDs to ensure researchers are correctly identified in system.

    ORCID Collect & Connect badge - Display DISPLAY
    BASE displays iDs to signal to researchers that it support the use of ORCID.

    ORCID Collect & Connect badge - Connect CONNECT
    BASE connects information to ORCID records for trusted sharing with others.
