KILT

As you may already have experienced it, your next NLP project may require you to work with knowledge-intensive tasks such as open-domain question answering or fact-checking. Benchmarking these knowledge intensive tasks can be difficult because these tasks require a huge knowledge source to feed off of (and things can get even harder when you have various knowledge sources to work with). As a result, a new benchmark from Facebook AI gives researchers a centralized baseline to start their research and benchmark model performance for these tough tasks, and it’s called KILT. It leverages an interface across tasks that are grounded on a single knowledge source: the 2019/08/01 Wikipedia snapshot containing 5.9M articles. Here are the tasks you’ll work with in KILT: fact checking, open-domain question answering, slot filling, entity linking, and dialogue.

Here’s what each Wiki record looks like:

{
'wikipedia_title': 'Email marketing',
'wikipedia_id': 1101759,
'text': ['p1', 'p2',...., 'pn'], # list of paragraph text
'anchors': [{"text":,"href":,"paragraph_id":,"start":,"end":} ] ,
'categories': 'comma separated list of categories'
'history': # some info from wikipedia, including original url
'wikidata_info': # wikidata info
}

Deleting Zeros

Our NN models are dense beasts, that love linear algebra (aka matrix multiplication). But that density isn’t very efficient. We can actually delete space in the matrix by getting rid of these zeros without losing performance. Without getting into the weeds of sparsity to spare you my naiveté on the subject, here’s François Lagunas’ intuitive take from his previous blog post:

“The sparsity of the matrix is the fraction of zeros against the size of the matrix

The pros? If you have a lot of zeros, you don’t have to compute some multiplications, and you don’t have to store them. So you may gain on size and speed, for training and inference.

The cons? Of course, having all these zeros will probably have an impact on network accuracy/performance. But to what extent? You may be surprised.”

FYI, for a more in-depth discussion/history on sparsity, you can check out HF’s new blog here. What’s cool is that you can begin your sparsity adventure with a new Hugging Face notebook that helps replace a linear block with a sparse one! It’s fairly straightforward to execute. For more intuition, checkout their notebooks below.

Data Readiness for Applied NLPers

Taking data seriously in NLP? Oftentimes, we can overlook pain-points that can arise when dealing with data prior to the start of project. As a result, folks at RISE in Sweden wrote an interesting white paper on data readiness for those applying NLP across businesses/institutions. Here’s a pithy example of what stakeholders should keep their eye on with respect to accessibility:

Does the data exist? Is the data required to address the task even recorded?

Data conversion and encoding. One of the major challenges faced within NLP is the conversion of documents from a source format, e.g., PDF, Word or Excel, to a format suitable for addressing the task at hand. In order to move beyond Band C, data conversion and encoding have to be in place.

Legal aspects of accessibility. Not only should the data be available to the intended team, but the team and the result of their efforts to produce a solution to the task at hand should also be cleared with respect to the legal aspects of accessing, and handling of the data. This include, e.g., the handling of personal identifiable information, and copyright issues.
