Overview

The med-ELIZA is a medical English LInking keywords finder for PubMed Zipped Archive, which searches keywords linking to each other in PubMed-medical-paper-abstracts in four phases. med-ELIZA analyzes the links between keywords occurring in the entire PubMed, in the same abstract, in the same sentence, and in the keyword in context (kwic).

The demonstration shown is an example for “study”, which is the most used keyword in the PubMed, and “aim”, which is a linking keyword to “study”.

What med-ELIZA does

  • ELIZA finds four types of linking keywords, neighboring (keyword in context, kwic), closely linking (in a sentence), loosely linking (in an abstract) keywords, and medical keywords (in the PubMed).

  • Thus, ELIZA assists you in writing medical English papers and in researching a specific medical subject linking to the keyword.

  • ELIZA uses the PubMed database updated daily.

Finding prepositions following a keyword

ELIZA searches and analyzes a keyword following a keyword.
Typing in  “found”, and clicking the “Search” button will show the right kwic search for “found”.

Frequency of next words

The word “found” is the 15th most used keyword in PubMed. The most used words following are “to be”.
Below the kwic search, ELIZA shows frequent words that follow “found”.

Frequently used prepositions that follow “found” are “in”, “between”, “for”, “at”, “with”, “on”, “among”, “by”, “during”, “from”, and “after”. Clicking the order number will bring you to the representing examples. Clicking the keyword will bring you to another kwic search for the keyword.

Left kwic and right kwic

Clicking the “left(kwic)” button will sort the search results in the order of the word left to the keyword. Clicking the “right(kwic)” button will switch the display back to the right kwic.

Showing the abstract

Clicking the order number at the left of each search result will show the abstract and the links to the PMID (PubMed ID) and DOI. Clicking the “abstract OFF” button brings you back to the kwic search results.

Navigation buttons

The navigation buttons “<<“, “<“, “>”, and “>>” will bring you back and forth around the search results.

kwic on/off

Clicking the “kwic OFF” button will show the search result in the full sentence. Clicking the “kwic ON” button will bring you back to the kwic display.

Finding linking words to a keyword

Type in “study”, click “Search” and click the “link” button will show the linking words to the word “study”.

The lists of linking words to “study” are associated words with “study” in the same sentence. The result suggests that medical study usually sets the aim of evaluating the effects of something relating to health. ELIZA also suggests that the synonyms of “aim” are “purpose” and “objective”, and those of “evaluate” are “assess”, “examine”, “investigate”, “determine”, and “compare”.

Further clicking the word in the list evokes another search. For instance, clicking “aim” will show a concatenated keywords search.
