EI mainly includes important documents in the field of engineering technology, including periodicals and conference documents, as well as some scientific and technological reports and monographs. There are three types of EI collections: EI core collections, non-core collections (Pageone collections) and conference papers. Since 2009, there is no difference between core retrieval and non-core retrieval, both of which are core retrieval. But it is also divided into periodical retrieval and conference retrieval. Namely JA type of source periodical and CA type of conference. In the professional title evaluation and the annual award of the school science and technology department, only the articles included in the EI core (EI CD version) are recognized.
EIVillage is a database platform, which contains two databases (EI and Inspec), so the tick mark in front of Inspec should be removed first. The method of distinguishing JA type from CA type. If the file type is judged as conference paper (CA), it is conference paper. If it is judged as Documenttype:Journalarticle(JA), it is a journal paper.
The source periodicals of EI periodicals are basically JA types. When evaluating the professional title, the grade is higher than the EI meeting type.
