Module tf.dataset.nodemaps
Node maps
When different versions of a TF dataset exist, it makes sense to map the nodes from the older version to nodes of the newer version.
If we have annotations on the older version (possibly created with considerable man-machine labour), we can use such node mappings to transfer the annotations to the newer version without redoing all the work.
Mapping the nodes consists of two stages:
- slot mapping This is very dependent on what happened between versions.
- node mappings per node type These can be generically constructed once we have a slot mapping.
This module contains the function makeVersionMapping which is a function to furnish node mappings
for node types given a slot mapping exists.
Nodes in general
The basic idea we use for the general case is that that nodes are linked to slots.
In TF, the standard oslots edge feature lists for each non-slot node
the slots it is linked to.
Combining the just created slot mappings between versions and the oslots feature,
we can extend the slot mapping into a general node mapping.
In order to map a node n in version V, we look at its slots s, use the already established slot mapping to map these to slots t in version W, and collect the nodes m in version W that are linked to those t. They are good candidates for the mapping.
Refinements
When we try to match nodes across versions, based on slot containment, we also respect
their otype. So we will not try to match a clause to a phrase.
We make implicit use of the fact that for most otype, the members
contain disjoint slots.
Multiple candidates
Of course, things are not always as neat as in the diagram. Textual objects may have split, or shifted, or collapsed. In general we find 0 or more candidates. Even if we find exactly one candidate, it does not have to be a perfect match. A typical situation is this:
We do not find a node m\in W that occupies the mapped slots exactly. Instead, we find that the target area is split between two candidates who also reach outside the target area.
In such cases, we make edges to all such candidates, but we add a dissimilarity measure. If m is the collection of slots, mapped from n, and m_1 is a candidate for n, meaning m_1 has overlap with m, then the dissimilarity of m_1 is defined as:
|m_1\cup m| - |m_1\cap m|
In words: the number of slots in the union of m_1 and m minus the number of slots in their intersection.
In other words: m_1 gets a penalty for
- each slot s\in m_1 that is not in the mapped slots m;
- each mapped slot t\in m that is not in m_1.
If a candidate occupies exactly the mapped slots, the dissimilarity is 0. If there is only one such candidate of the right type, the case is completely clear, and we do not add a dissimilarity value to the edge.
If there are more candidates, all of them will get an edge, and those edges will contain the dissimilarity value, even if that value is 0.
Diagnostic labels
We report the success in establishing the match between non-slot nodes. We do so per node type, and for each node type we list a few statistics, both in absolute numbers and in percentage of the total amount of nodes of that type in the source version.
We count the nodes that fall in each of the following cases. The list of cases is ordered by decreasing success of the mapping.
bunique, perfect: there is only one match for the mapping and it is a perfect one in terms of slots linked to it;dmultiple, one perfect: there are multiple matches, but at least one is perfect; this occurs typically if nodes of a type are linked to nested and overlapping sequences of slots;cunique, imperfect: there is only one match, but it is not perfect; this indicates that some boundary reorganization has happened between the two versions, and that some slots of the source node have been cut off in the target node; yet the fact that the source node and the target node correspond is clear;fmultiple, cleanly composed: in this case the source node corresponds to a bunch of matches, which together cleanly cover the mapped slots of the source node; in other words: the original node has been split in several parts;emultiple, non-perfect: all remaining cases where there are matches; these situations can be the result of more intrusive changes; if it turns out to be a small set they do require closer inspection;anot mapped: these are nodes for which no match could be found.

# Node maps
When different versions of a TF dataset exist, it makes sense to map the nodes from the
older version to nodes of the newer version.
If we have annotations on the older version
(possibly created with considerable man-machine labour),
we can use such node mappings to transfer the annotations to the newer version without
redoing all the work.
Mapping the nodes consists of two stages:
1. **slot mapping** This is very dependent on what happened between versions.
1. **node mappings per node type** These can be generically constructed once
we have a slot mapping.
This module contains the function `makeVersionMapping` which is a function to furnish node mappings
for node types given a slot mapping exists.
# Nodes in general
The basic idea we use for the general case is that that nodes are linked to slots.
In TF, the standard `oslots` edge feature lists for each non-slot node
the slots it is linked to.
Combining the just created slot mappings between versions and the `oslots` feature,
we can extend the slot mapping into a general node mapping.
In order to map a node \\(n\\) in version \\(V\\), we look at its slots \\(s\\),
use the already established *slot mapping* to map these to slots
\\(t\\) in version \\(W\\),
and collect the nodes \\(m\\) in version \\(W\\) that are linked to those \\(t\\).
They are good candidates for the mapping.
# Refinements
When we try to match nodes across versions, based on slot containment, we also respect
their `otype`. So we will not try to match a `clause` to a `phrase`.
We make implicit use of the fact that for most `otype`, the members
contain disjoint slots.
# Multiple candidates
Of course, things are not always as neat as in the diagram.
Textual objects may have split, or shifted,
or collapsed.
In general we find 0 or more candidates.
Even if we find exactly one candidate, it does not have to be a perfect match.
A typical situation is this:
We do not find a node \\(m\\in W\\) that occupies the mapped slots exactly.
Instead, we find that the target area is split between two candidates who
also reach outside the target area.
In such cases, we make edges to all such candidates, but we add a dissimilarity measure.
If \\(m\\) is the collection of slots, mapped from \\(n\\), and \\(m_1\\) is a candidate
for \\(n\\), meaning \\(m_1\\) has overlap with \\(m\\),
then the *dissimilarity* of \\(m_1\\) is defined as:
$$|m_1\\cup m| - |m_1\\cap m|$$
In words: the number of slots in the union of \\(m_1\\) and \\(m\\)
minus the number of slots in their intersection.
In other words: \\(m_1\\) gets a penalty for
* each slot \\(s\\in m_1\\) that is not in the mapped slots \\(m\\);
* each mapped slot \\(t\\in m\\) that is not in \\(m_1\\).
If a candidate occupies exactly the mapped slots, the dissimilarity is 0.
If there is only one such candidate of the right type, the case is completely clear,
and we do not add a dissimilarity value to the edge.
If there are more candidates, all of them will get an edge,
and those edges will contain the dissimilarity value, even if that value is \\(0\\).
# Diagnostic labels
We report the success in establishing the match between non-slot nodes.
We do so per node type, and for each node type we list a few statistics,
both in absolute numbers and in percentage of the total amount of nodes of that
type in the source version.
We count the nodes that fall in each of the following cases.
The list of cases is ordered by decreasing success of the mapping.
* `b` **unique, perfect**:
there is only one match for the mapping and it is a perfect one
in terms of slots linked to it;
* `d`
**multiple, one perfect**:
there are multiple matches, but at least one is perfect;
this occurs typically if nodes of a type are linked to nested
and overlapping sequences of slots;
* `c`
**unique, imperfect**:
there is only one match, but it is not perfect;
this indicates that some boundary reorganization has happened
between the two versions,
and that some slots of the source node have been cut off in the target node;
yet the fact that the source node and the target node correspond is clear;
* `f`
**multiple, cleanly composed**:
in this case the source node corresponds to a bunch of matches,
which together cleanly cover the mapped slots of the source node;
in other words: the original node has been split in several parts;
* `e`
**multiple, non-perfect**:
all remaining cases where there are matches;
these situations can be the result of more intrusive changes;
if it turns out to be a small set they do require closer inspection;
* `a`
**not mapped**:
these are nodes for which no match could be found.

If you have a dataset with several features, and if there is a node map between

The naive approach per feature is:
For each node in the old version that has a value for the feature,
map the node to the new version.
That could be several nodes.
Then give all those nodes the value found on the node in the old set.
The problem with that is this:
Suppose node `n` in the old version maps to nodes `p` and `q` in the
new version, but not with the same quality.
Suppose the value is `v`. Then the feature assignment will assign
`v` to nodes `p` and `q`.
But there could very well be a later node `m` with value `w` in the old version
that also maps to `p`, and with a lower quality.
Then later the node `p` in the new version will be assigned the value `w`
because of this, and this is sub optimal.
So we make sure that for each feature and each node in the new version
the value assigned to it is the value of the node in the old version that
maps with the highest quality to the new node.
Parameters
----------
featureNames: tuple
The names of the features to migrate.

location: string, optional None

The APIs for both `va` and `vb` may be partial TF APIs, which means that they only have to provide the `tf.core.nodefeature.NodeFeatures` (`F`) and `tf.core.edgefeature.EdgeFeatures` (`E`) APIs.

Migrate features from one version to another based on a node map.
If you have a dataset with several features, and if there is a node map between the versions, you can migrate features from the older version to the newer.
The naive approach per feature is:
For each node in the old version that has a value for the feature, map the node to the new version. That could be several nodes. Then give all those nodes the value found on the node in the old set.
The problem with that is this:
Suppose node
nin the old version maps to nodespandqin the new version, but not with the same quality. Suppose the value isv. Then the feature assignment will assignvto nodespandq.But there could very well be a later node
mwith valuewin the old version that also maps top, and with a lower quality. Then later the nodepin the new version will be assigned the valuewbecause of this, and this is sub optimal.So we make sure that for each feature and each node in the new version the value assigned to it is the value of the node in the old version that maps with the highest quality to the new node.
Parameters
featureNames:tuple- The names of the features to migrate. They may be node features or edge features or both.
location:string, optionalNone- If absent, the migrated features will be saved in the newer dataset. Otherwise it is a path where the new features should be saved.
silent:string, optionalNone- See
TimestampThis will override thesilentsetting that has been used when creating theVersionsobject.
