I have a simple query.I have searched it many times but not getting satisfactory result.
I want to generate a diagram for all the entities(Code first) and relationship between them.I have total 19 classes so far.I have seen some articles on Reverse engineer code first.But I would like to see A diagram which looks like as created in Database First Approach.
So far, have installed Entity framework Power tools in my visual studio 2013 But from there only getting two options---
1>Reverse engineer code first
2>Customize reverse engineer template
thanks in advance!
You can use Entity Framework Powertools "View Entity Data Model(Read-only)" feature https://msdn.microsoft.com/en-us/data/jj593170.aspx

I'm new to NLP. I am looking for recommendations for an Annotation tool to create a labeled NER dataset from raw texts.
In details:
I'm trying to create a labeled data set for specific types of Entities in order to develop my own NER project (rule based at first).
I assumed there will be some friendly frameworks that allows create tagging projects, tag text data, create a labeled dataset, and even share projects so several people could work on the same project, but I'm struggling to find one (I admit "friendly" or "intuitive" are subjective, yet this is my experience).
So far I've tried several Frameworks:
I tried LightTag. It makes the tagging itself fast and easy (i.e. marking the words and giving them labels) but the entire process of creating a useful dataset is not as intuitive as I expected (i.e. uploading the text files, split to different tagging objects, save the tags, etc.)
I've installed and tried LabelStudio and found it less mature then LightTag (don't mean to judge here :))
I've also read about spaCy's Prodigy, which offers a paid annotation tool. I would consider purchasing it, but their website only offers a live demo of the the tagging phase and I can't access if their product is superior to the other two products above.
Even in StackOverflow the latest question I found on that matter is over 5 years ago.
Do you have any recommendation for a tool to create a labeled NER dataset from raw text?
⚠️ Disclaimer
I am the author of Acharya. I would limit my answers to the points raised in the question.
Based on your question, Acharya would help you in creating the project and upload your raw text data and annotate them to create a labeled dataset.
It would allow you to mark records individually for train or test in the dataset and would give data-centric reports to identify and fix annotation/labeling errors.
It allows you to add different algorithms (bring your own algorithm) to the project and train the model regularly. Once trained, it can give annotation suggestions from the trained models on untagged data to make the labeling process faster.
If you want to train in a different setup, it allows you to export the labeled dataset in multiple supported formats.
Currently, it does not support sharing of projects.
Acharya community edition is in alpha release.

Doccano is another open-source annotation tool that you can check out https://github.com/doccano/doccano
I have used both DOCCANO (https://github.com/doccano/doccano) and BRAT (https://brat.nlplab.org/).
Find the latter very good and it supports more functions. Both are free to use.
I am new to Alteryx and am trying to use it for analysing unstructured data. I have a column of description in text form and I intend to use the K-Means Clustering tool for topic modelling. For K-means to work on text, I will need to convert my text into a Document Term Matrix (DTM) so that they appear as continuous variables to the clustering tool. However, I am struggling to find a way I can convert my text to a DTM.
Does anyone know a way to do so? I am currently looking at the R tool but am not exactly sure how to start too. Hoping that all of you experts here can help me out!
I have looked through posts on text analysis and realized that most fell back on the Microsoft Azure ML Text Analysis Macro. However, I would like to avoid using the macro (to not be restricted to limited runs every month for scalability) and instead use tools that are available in Alteryx.
Thanks to everyone in advance!
with Alteryx being more of a pictoral drag-and-drop workflow, it's not trivial to explain here, however I've created the following workflow and included the actual workflow itself on the Alteryx forum here. The workflow utilizes term frequencies from Inauguration speeches but should apply to any collection of documents. It just splits the words based on various non-numeric characters and does a summary. This is what the workflow looks like:
I am new in Hybris 6, i would like to create a simple eCommerce store where i can select products and check out as normal using the basic recipe. I would like to know how to do that from END to END. I know the whole theory and i have the material the only thing i am interested in in the various steps i must follow to create a fully functional simple store. Currently i can do the data modelling and classifications, import data using ImpEx, I can view and customize the available electronics and apparel stores however the problem is i want to create mine from scratch.
Use the modulegen ant target, it creates all you need for your future store implementation.

How can I get a list of linked work item IDs for a set of work items?
Excel-hosted queries preferred. API Sample is acceptable.
Direct DB table query is acceptable (read-only and unsupported of course!)
Many thanks in advance! -Zephan
MORE INFORMATION
UPDATE: No answers for my original Q so broadening scope of acceptable answers as follows:
Answer for TFS2015 (migrating very shortly) or TFS2013 (potentially useful for TFS2015) is preferred over TFS2010
Coding acceptable if there are any APIs or PowerShell cmdlets (MS or community).
Connecting directly (read-only!) to TFS DB tables is acceptable (source tables and related relationship link table names). Yes, directly referencing TFS DB tables is VERY unsupported, read-only, and "AT YOUR OWN RISK." Still beats having to manually copy/paste data or reconstruct list of links in Excel.
ORIGINAL QUESTION & DETAILS
My team uses TFS2010 (soon 2013 or hoping 2015) and VS2010-2015. I need to support traceability reports and analyze/quantify our coverage of ~300 Test Case work items linked to ~400 Requirement work items. Direct Link and Tree queries are close but don't give me related links on the same row as parent work item. Many thanks in advance for your suggestions and any related code fragments.
Example:
3 test cases (Test1, Test2, Test3)
4 Requirements (Req1, Req2, Req3, Req4)
For simplicity let's just use TFS work item IDs to represent each TestN and ReqN. In actuality, I have a keyword to identify my validation requirements (separate from the 1,000's of other requirements in this Team Project). The only Test Case WI I care about for this problem are those linked to one or more Validation Requirement trace-ability.
Scenarios:
1:1 (simple) Test1 is linked to Req1
1:2 (1:n) Test2 is linked to Req2 and Req3
2:1 (n:1) Test3 (and Test2) are both linked to Req3
0:1 (Requirement missing Test coverage) Req4 has no test case links
I have a good coverage gap query by creating a Direct Link query for all Requirements then set "linking filters" to Only return items that do not have the specified links.
Desired output (all tests with list of related work items):
|Test1 | Req1 |
|Test2 | Req2, Req3 |
|Test3 | Req3 |
For row #2 I am OK with other separators or even entire list using same separator (.CSV or TAB delimited).
Skip right to answer now if you have a tidy answer. If not then I added considerable RELATED RESEARCH info below to help kick-start an idea that fits the need! Especially since this hasn't been discoverably solved in the last 5 years :-).
RELATED RESEARCH (loooong but may be useful)
1. Visual Studio Queries
Flat Queries should support a list of linked items out-of-the-box... but it does not. RelatedLinkCount field is handy for knowing if there are any links to chase, but that's it for flat queries.
Direct Link queries give a list of all direct links, but the related IDs are on rows below the parent work item. I am seriously considering creating a formula to look on the next X rows to build a list of IDs, but this would be fragile especially when over 3 requirements are linked to same test. Still might solve 80% of my tracing needs.
Tree Queries also show links, but on different rows. Additionally they tend to follow just one link type. Ideally I will need list of User Requirements linked to Functional Requirements linked to Test Case(s).
2. Tools / Plug-ins
SmartExcel4TFS (eDEVTech, http://www.modernrequirements.com/smartexcel4tfs/) has 3 reports it supports, but none get me the core data I need in easily used format. At least it is FREE if you have an MSDN Premium subscription.
Requirements to Tests Trace Matrix is super-interesting. Alass, right now I need to go the other way (Requirements linked to a given test case). Also it merges cells and has sub-sections that are hard to manipulate I think. (I may revisit this option though.)
Intersection Traceability Matrix report is WAY too wide for a full 300 x 400 grid :-O.
Work Item Decomposition Matrix also didn't give me desired contents. (though frankly I've forgotten this report layout from when I checked ~1 month ago.)
3. TFS API calls
I have actually avoided this route in favor of native Excel solution... but if I can get an example of Excel VBA code (or other code with link to calling within Excel) I may go this route. At this point I don't have time to dig into rolling my own... but this would be cool assuming performance is acceptable.
Relevant API/code fragments:
Retrieving TFS Results from a Tree Query (Blogs.msdn.com 2012.02.22) - Looks like this would get me the data I need, but it is not in Excel so I'd need a bridge example of some sort calling this within Excel.
Retrieving work items and their linked work items in a single query using the TFS APIs (stackoverflow.com 2012.01.12) - Also looks very promising, but not connected to Excel. Gives hints for 2 level and 3 level nested links and performance consideration (don't make second call for each item returned!)
Retrieving work items using the Team Foundation Server API (pwee167.github.io 2012.09.18) - Excellently written introductory walkthrough blog posting to learn how to build an (ASP.Net MVC3) app that calls TFS APIs to run Flat or Tree queries. Start here if writing C# (which I could do but don't have time/justification unless easy example to integrate with Excel).
How can I query work items and their linked changesets in TFS? (stackoverflow.com 2011.05.10) - I don't need changesets but this has VB code to instantiate new TfsTeamProjectCollection which might work directly in Excel VBA (assuming proper reference is found and added)
var projectCollection = new TfsTeamProjectCollection(
new Uri("http://localhost:8080/tfs"),
new UICredentialsProvider());
OK, that's everything I have gathered on this problem. Please help contribute with the missing magic tool/snippet or follow the info above to build that last bit I have not had time to prototype & debug. Many thanks in advance!! -Zephan
In specific, I would like to maintain a baseline set of requirement work items but also develop a second subset of slightly modified requirements for a related product without 'copying' them to a second project.
In Polarion 2012 you can actually branch whole document with those workitems. I guess that's feature exactly for you.
