Text Index Parameter in concept insights gives only one instance of concept occurance -

-

i have multiple mentions of concept (e.g. "gold") in document. concept insights' conceptual search return gold concept , 1 text index concept (usually first occurrence, not always). there specific reason why concept insights' conceptual search ignores other mentions of "gold" in document? interested in pulling snippets of text around occurrences of concept. have been great if got text index mentions of concept. there way it, other doing string match @ end.

thanks in advance help!

the conceptual search concept insights not ignore several mentions of same (or related) concept within document. in fact, service uses information reinforce system's understanding of concept areas covered in each document.

however, true in "explanation" of why document related document, /conceptual_search endpoint returns select set of concepts. because system trying show diversity of concepts justify connection between query , document, can omit repeated concepts part of "explanation" (you can think "explanation" akin snippet of text traditional search engine may suggest user why document may relevant; not complete story of associations found within document).

that being said, can concepts extracted within document using /annotations endpoint: get /v2/corpora/{account_id}/{corpus}/documents/{document}/annotations.

(documentation: https://watson-api-explorer.mybluemix.net/apis/concept-insights-v2#!/corpora/getdocumentannotations)

for every annotation in document, concept id along positions in text occurrence of document. so, example above, can:

1) call /conceptual_search endpoint retrieve documents relevant query, along number of explanation concepts (concepts tie document query); found concept question gold.

2) call /{document}/annotations returned document, looking additional occurrences of "explanation concepts" (gold) within selected document. should able build list of gold occurrences (along lists of other explanation concepts), cover entire document.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
