Basic use:

Click each title line to read the text.

[1] Cross Check

• Select items, ---> then relevant topic-words are marked. [illustration]
  • Select some items in the title list (left window) by clicking the small squares.
  • Then the squares of the selected items turn red, and
  • topic words contained in one of these selected items are marked (surrounded by red borders).
  • Use Clear button below the title list for clearing the selections.
• Select topic-words, ---> then relevant items are marked. [illustration]
  • Select some topic words by clicking topic-words with shift key.
  • Then the selected topic-words turn orange, and
  • items (titles) containing these selected topic-words are marked with red check marks.
  • The thickness of each check mark show how many kinds of topic words are included in each item.
    • If you do not find check marks, use the vertical scroll bar to find them.
    • If you click topic-words without shift key, then the previously selected topic words return un-selected.
    • You can select multiple topic-words by designating a rectangular region by mouse-dragging starting from a background (white) point.
• Gather button gathers marked items to the top of the title list in the order of their thickness, that is to say, in the order of relevance to the selected topic words. [illustration]
  • Restoration of original order of search results.
    When no topic words are selected (therefore no articles are marked), Gather button restore the original order of search results. So, the original order can be restored anytime by clearing the selection of topic words and by clicking Gather button.
• Propagate button (under the topic-word graph) extends the selection of topic-words in a manner that those topic words linked to already selected topic-words are also selected. [illustration]
  • When you have selected only a small number of topic-words (such as only one), doing Propagate before Gathering is effective because such items related not only to the directly selected words but also to their neighboring words get thicker check marks.

[2] Document Association --- feedback with selected articles --- [illustration]

• Select articles of your interest by clicking their small squares.
• Assoc button (left-bottom corner) executes associative search (similarity-based search) using the selected items as search keys, and returns search results in the order of relevance to the selected items.

[3] Topic-Word Association --- feedback with selected topic-words --- [illustration]

• Select interesting topic-words in the topic-word-graph.
  • See the details of selecting method in [1] Cross Check .
• TAssoc button (right-bottom corner) executes search with selected words as search keys.
