At a glance

At its simplest, an expert search query looks like this:

[3]:

%%dsl

identify experts from concepts "malaria OR \"effective malaria vaccine\" OR \"effective prevention\""
      using publications
      where year >= 2015
return experts[basics]

[3]:

<dimcli.DslDataset object #4415239408. Dict keys: '_copyright', '_stats', '_version', 'experts'>

The query takes a list of concepts defining the expertise you’re looking for, plus other parameters defining the pool of publications to be used, and it returns a list of researchers sorted by relevance.

Often though, we start from some text and want to find experts relevant to that text (as opposed to starting from concepts).

The expert identification workflow, in such a case, consists of two steps:

  1. Concepts extraction from text

  2. Expert identification using concepts

In the first step, the user extracts concepts from an abstract. The user can review and modify the list of extracted concepts and then feed it into the actual expert identification workflow. In the following sections we will go though these steps in details.

Step 1: Concept Extraction

What are concepts?

Concepts are noun-phrases automatically extracted from a document’s abstract as well as the rest of the Dimensions database, which is used to weight their importance and relevance within the document’s field of study (see also the official documentation: searching using concepts).

For instance, the phrases machine learning and neural network will be considered very relevant in a computer science paper, while project and study will have their relevance scores low as they are generic phrases.

Extracting concepts with the DSL

Extracting concepts is implemented using the extract_concepts DSL function. This is the syntax:

extract_concepts("publication abstract")

This query will return a list of extracted concepts, ordered by weight, in descending order. For example:

[5]:

abstract = """We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions,
metallic, and of remarkably high quality. The films are found to be a two-dimensional semimetal with a tiny overlap between
valence and conductance bands, and they exhibit a strong ambipolar electric field effect such that electrons and
holes in concentrations up to 10 per square centimeter and with room-temperature mobilities of approximately 10,000 square
centimeters per volt-second can be induced by applying gate voltage.
"""

abstract = abstract.replace("\n", " ")

res = dsl.query(f"""extract_concepts("{abstract}")""")

CONCEPTS = res['extracted_concepts']

pd.DataFrame(CONCEPTS)

[5]:
0
0 films
1 ambipolar electric field effect
2 two-dimensional semimetal
3 electric field effects
4 room temperature mobility
5 conductance band
6 field effects
7 graphitic films
8 centimeters
9 gate voltage
10 semimetals
11 electrons
12 atoms
13 holes
14 square centimeter
15 metallic
16 ambient conditions
17 band
18 valence
19 voltage
20 mobility
21 high quality
22 overlap
23 effect
24 conditions
25 concentration
26 quality

Step 2: Expert Identification

Extracted concepts, from step one, can be used in a identify experts queries, for example:

identify experts from concepts "+malaria OR \"effective malaria vaccine\" OR \"effective prevention\""
      using publications
      where research_org_countries is not empty
          and year >= 2013
return experts[basics]
      limit 20 skip 0
      annotate organizational, coauthorship overlap
          with ["ur.016204724721.35", "ur.012127355561.32"]

Returned experts are ordered by their relevance.

A few important things to remember:

  1. Sources. Experts identification can use either publications or grants (when not specified, publications are used)

  2. Default connector is AND. When multiple concepts are provided, these are transformed automatically into an AND query. To match any of the concepts, one should then explicitly add OR connectors.

  3. Where conditions. It is possible to specify where-filters but that’s not required. Fields available for filtering are exactly the same as the ones in standard search expressions.

  4. Pagination. Similarly, the paging-phrase is optional. By default, the top 20 experts get returned - using limit/skip it is possible up to a maximum of 200.

  5. Overlap annotations. Annotating results with organizational and/or coauthorship overlap will produce another JSON object for each identified expert. This object has two parts.

    • The Organizational overlap is defined as a boolean value that is true if the expert and the researchers from the query have the same current research organization.

    • The Coauthorship conflict is defined as the number documents the expert has coauthored with any of the researchers provided in the query, in the last three years.

Example 1. Basic query using concepts

[6]:

# take the top 15 concepts
some_concepts = " ".join(['"%s"' % x for x in CONCEPTS[:15]])

q = f"""
        identify experts
            from concepts "{dsl_escape(some_concepts)}"
        return experts
        """

print("Query:\n======", q)

dsl.query(q).as_dataframe()

Query:

Example 5. Query with MUST/NOT Operators

By default, the string containing a list of concepts is interpreted as a sequence of AND clauses. That is, the query tries to match the highest number of concepts without any preference.

It is possible to specify MUST/NOT rules with concepts by passing them via a string and using the + and - operators.

Note: please remember that concepts phrases (= concepts that are composed by more than one word) need to be wrapped using quotes, and the quotes need to be escaped with a \.

Additional resources: shortcut functions included in Dimcli

Dimcli includes a number of ‘shortcut’ Python functions that make it easier to work with the expert identification API.

[13]:

from dimcli.functions import extract_concepts, identify_experts, build_reviewers_matrix

extract_concepts

A Python wrapper for the DSL function extract_concept (see source).

Extract concepts from any text. Text input is processed and extracted concepts are returned as an array of strings ordered by their relevance

[14]:

%%extract_concepts

We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions,
 metallic, and of remarkably high quality. The films are found to be a two-dimensional semimetal with a tiny overlap between
 valence and conductance bands, and they exhibit a strong ambipolar electric field effect such that electrons and
 holes in concentrations up to 10 per square centimeter and with room-temperature mobilities of approximately 10,000 square
 centimeters per volt-second can be induced by applying gate voltage.

identify_experts

A Python wrapper for the full expert identification workflow (see source).

This wrapper provide a simpler version of the expert identification API. It is meant to be a convenient alternative for basic queries. For more options, it is advised to use the API directly.

Build a reviewers matrix

Generates a matrix of candidate reviewers for abstracts, using the expert identification workflow (see source).

If the input abstracts include identifiers, then those are used in the resulting matrix. Alternatively, a simple list of strings as input will result in a matrix where the identifiers are auto-generated from the abstracts order (first one is 1, etc..).

[16]:

abstracts = [
     {
     'id' : 'A1',
     'text' : """We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions,
