I am new to semantic web and trying to understand. I am using Apache Stanbol
I am seding text to enhance using Restful service and getting a Structure like

selected-text: Cologne
start: 1451

What I wanted to ask is what does start, end means? and relation contains a comma seprated list of IDs. How may I access the related IDs using SPARQL
start: The start character position within the plain text version of the parsed content. Note that the plain text version can be
retrieved by using the multi-part content item support of the Stanbol
Enhancer RESTful API.
end: The end character position. This MUST only be present of "fise:start" is also defined.
relation: Specifies that the current fise:Enhancement has a relation to an other fise:Enhancement. Values need to be resources of the "rdf:type" "fise:Enhancement".

I'm trying to use version 2 of the Twitter API to achieve the goal described in the title. Here's what I have tried so far:
Listening to sample stream (1% of Twitter's stream): Almost all the returned Tweets don't have geo-info when following this approach. And it makes sense, since only 0.85% of all Tweets have geo-info.
Listening to a filtered stream with only one rule setup, namely the has:geo rule. But it's returning the following 2 errors:
"Reference to invalid operator 'has:geo'. Operator is not available in current product or product packaging. Please refer to complete available operator list at https://developer.twitter.com/en/docs/twitter-api/enterprise/rules-and-filtering/operators-by-product. (at position 5)".
"has/is/lang/sample cannot be used as a standalone operator (at position 1)".
Here's the rule I'm adding to the stream:
[
{
"value": "has:geo",
"tag": "contains geo-info",
},
]
I need help in solving both shown errors, or a suggestion describing a third different approach.
I see this question has been discussed on the Twitter Community forum: https://twittercommunity.com/t/how-to-listen-to-tweets-that-only-contains-geo-info-from-twitter-stream/162905/2
Short answer:
The has:geois one of several query operators that can not be used in a standalone fashion, and must be paired with keywords and other non-boolean operators.
The has:geo operator is only available in academic and paid packages.
I just learned to use "hypermedia rest API" on openproject
I want to use "filter" param with "_links" properties on API but not know-how
Example:
http:/<my_domain>/target/api/v3/projects/design/work_packages?filters=[{"updatedAt":{"operator":"<>d","values":["2017-06-10T22:00:00Z","2017-07-05T22:00:00Z"]}, "_links":{"type":{"title":{"operator":"=","values":["Box"]}}}]
==> My Question:
i not known use to "_links":{"type":{"title":{"operator":"=","values":["Box"]} params filter. Now, result is not filter for "_links"
And show me books name to learn API for to beginner
? (https://www.oreilly.com/library/view/restful-web-clients/9781491921890/ch04.html#callout_hal_clients_CO1-1) -> is this ok?
Help me, please!
Thanks!

What I understood you wanting to achieve is getting all work packages in the project "design" that have been updated last within a certain time interval and that are of the type "Box".
The filters in OpenProject do not differentiate between native properties (like updatedAt) and linked resources (like type) when it comes to the structure of the filters. The syntax is always
{"<name of the filter>": {"operator": "<operator>": "values": [<list of values>]}}
When it comes to the filter values however, there is a difference. For linked resource the client is expected to use the id whereas native value like an integer, string or date is required for the native properties.
For your request the above requires the client to issue the following query:
GET http://domain/target/api/v3/projects/design/work_packages?filters=[{"updatedAt":{"operator":"<>d","values":["2017-06-10T22:00:00Z","2017-07-05T22:00:00Z"]}}, {"type":{"operator":"=", "values":["10"]}}]
I took the id of 10 for the type "Box" out of the screenshot you provided.
To get the filter values of all available filter you can call
POST http://domain/target/api/v3/queries/form
with a body of
{"name":"default","_links":{"project":{"href":"/api/v3/projects/design"}}}
The response will list all available filters in the _embedded/schema/_embedded/filtersSchema array.
I have a question regarding the alfresco FTS/lucene search. It is known that in the search query some special characters have to be escaped, like space (by _x0020_).
But it turned out that if folder's name first chatacter is a digit, it should also be escaped. It can be easily tested in Node Browser by creating a folder, like 123456 and navigate to the parent folder in node browser (in my case I have following folder structure: */2017/123456/):
Primary Path: /app:company_home/st:sites/<some-folders>/cm:_x0032_017/cm:_x0031_23456
^this is 2 ^ and this is 1
If I don't ecape first character of the folder I have 500 error returned.
Why is that, I tried to find something relevant in Alfresco documentation, but didn't manage to.
Alfresco v.4.2.0
Lucene search uses ISO 9075 codification (SQL) like similar frameworks, so we need to encode the path elements. It would be nice if the API hides this requirement like the browser url but you could use ISO9075Encode to do the job.
I make a Wikidata search request like this (autocomplete use case):
https://www.wikidata.org/w/api.php?action=wbsearchentities&format=json&language=en&type=item&continue=0&search=photog
And the service returns a JSON response thus
{
id: "Q11633",
url: "//www.wikidata.org/wiki/Q11633",
description: "art, science and practice of creating durable images by recording light or other electromagnetic radiation",
label: "photography"
}
But how do I look up to get retrieve the content?
I can only find a title search which does not recognize the Q parameter. It only recognizes titles.
https://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=content&format=json&titles=Photography
You want to use wbgetentities, another method of WikiData's extension to the MediaWiki API (WikiBase). In its most basic form, it looks like this:
api.php?action=wbgetentities&ids=Q11633
You probably want to reduce the size of the reply, by specifying what you what to know about the entity, using the props parameter.
I am entirely new to API, so sorry if the question is silly.
I would like to get all images in a category in Commons let's say X, but exclude those which are also in another one (Y). I do not understand if I can actually do this.
https://commons.wikimedia.org/w/api.php?action=query&list=categorymembers&cmtype=file&cmtitle=Category:X
will get all of them, how to exclude some?
moreover I would like in the result to have the description of the images, not just the name of the file, is that possible?
MediaWiki has - by default - no built-in support for category building and querying intersections. To accomplish this task, extensions or external tools or multiple API queries and result processing is required.
CirrusSearch API
On Wikimedia Commons, like on the whole Wikimedia Wiki farm, CirrusSearch powers filtered search, including search for category intersections and is also available through API (action=query&list=search&srsearch=incategory:A+-incategory:B, this is Category:A minus Category:B).
FastCCI
One of the tools I can recommend (because it's a dedicated high-performance solution and actually running) is fastcci, developed by Daniel Schwen; specifically for Wikimedia Commons, there is already a database maintained and a webservice running but it's possible to set it up for any wiki, provided the tool set has a host to run on and has database access.
Query
Consider the following query URL:
https://fastcci.wmflabs.org/?c1=3302993&c2=15516712&d1=0&d2=0&s=200&a=not&t=js
https://fastcci.wmflabs.org/ - Host Wikimedia Commons fastcci runs on
c1 - ID of category 1
c2 - ID of category 2
d1 - depth of category 1 to search in (fastcci by default considers sub-categories)
d2 - depth of category 2 to search in (fastcci by default considers sub-categories)
s - Number or results to return
o - Offset
a - conjunction
t - connection type (t=js for a JSONP response; otherwise assumes being used as websocket)
Response
fastcciCallback( [ 'RESULT 27572680,0,0|1675043,0,0|27577015,0,0|27577043,0,0|27577106,0,0|27576896,0,0|27576790,0,0|23481936,0,0|17560964,0,0|11009066,0,0', 'OUTOF 10', 'DBAGE 378310', 'DONE'] );
RESULT followed by a | separated list of up to 50 integer triplets of the form pageId,depth,tag. Each triplet stands for one image or category
Resources
Sample client side implementation - to see it in action, just visit any category and next to the Good pictures button in any category page.
Example is FilesOf('Category:Saaleck') - FilesOf('Category:Rapeseed fields in Saxony-Anhalt')
Server application
Presentation on YouTube

A note on pageIDs
page IDs → page titles: GET /w/api.php?action=query&pageids=page_IDs_separated_by_pipe
page titles → page IDs: GET /w/api.php?action=query&titles=Titles_separated_by_pipe
AFAIK, there is no way to get that directly using the API. But, assuming both categories are reasonably small, you could get all images from both of them and then compute the complement in your code.
To retrieve the description, you can use prop=imageinfo&iiprop=extmetadata&iiextmetadatafilter=ImageDescription.
In the context of your example query, it would look like this:
https://commons.wikimedia.org/w/api.php?action=query&generator=categorymembers&gcmtype=file&gcmtitle=Category:X&prop=imageinfo&iiprop=extmetadata&iiextmetadatafilter=ImageDescription
