Data Computing


We are able to assist you with the completion on the most complicated computation tasks. You could even CUSTOMIZE formulas or algorithms.

Bear in mind that WE can DO much much more than the followings:

Basic Computation


We support all computations defined in EXCEL on HUGE datasets (Above 10M+).

  • Sum (accumulative)
  • Average (accumulative, moving)
  • Median (accumulative, weighted)
  • Variance (accumulative, population, sample)
  • Standard Deviation (accumulative, unbiased sample)
  • Top 5%, 10%, 15%, 20% percentile
  • Down 5%, 10%, 15%, 20% percentile
  • Much much more....

Graph/Network


We support graph computation on four types of graphs, i.e., Undirected graphs with self loops, Directed graphs with self loops, Undirected graphs with self loops and parallel edges, Directed graphs with self loops and parallel edges, Consistently ordered graphs.

  • Centrality. Degree, Eigenvector, Closeness, Current Flow Closeness, (Shortest Path) Betweenness, Current Flow Betweenness, Communicability Betweenness, Load, Subgraph, Harmonic Centrality, Reaching.
  • Approximation. Connectivity, K-components, Clique, Clustering, Dominating Set, Independent Set, Matching, Ramsey, Vertex Cover.
  • Components. Connectivity, Strong connectivity, Weak connectivity, Attracting components, Biconnected components, Semiconnectedness.
  • Link Analysis. PageRank, Hits.
  • Shortest Paths. shortest_path, all_shortest_paths, hortest_path_length, average_shortest_path_length.
  • Structural holes. constraint, effective_size, ocal_constraint.
  • Traversal. Depth First Search, Breadth First Search, Beam search, Depth First Search on Edges.
  • Tree. Recognition, Branchings and Spanning Arborescences, Encoding and decoding, Operations, Spanning Trees, Exceptions.
  • Much much more....

Date & Time


We support Date & Time calculations.

  • Time and Date Duration. Calculate duration, with both date and time included.
  • Date Calculation. Add or subtract days, months, years.
  • Weekday. What Day is this Date?
  • Week Number. Find the week number for any date.
  • Convert any formats of date & time to standard unix timestamp and vice versa.
  • Time Zone Conversion. Convert date & time to any time zones.
  • Much much more....
